Is it really worth trying to force him to be "daddy" and pay child support when he's made it very clear he doesn't want to be involved? As PPs have said there's no guarantee you'll actually get that few hundred dollars a month, and if he does pay and at some point decides to be involved in the child's life, you'll likely have to send your child off to another state for a couple months every year with someone that you really don't know at all anymore. The kids I know whose parents live in different states have to go visit for a week at Christmas and 6 weeks during the summer. It's your choice, but carefully consider the possible long-term ramifications before you make the decision.
